Physical DescriptionLead fluoride is an odorless white solid. Sinks in water. (USCG, 1999)White to colorless crystals[HSDB]
Other Experimental PropertiesLead is derived from the decay of radon. /Inorganic lead/Natural lead is a mixture of four stable isotopes: Pb-204 (1.4%), Pb-206 (25.2%), Pb-207 (21.7%) and Pb-208 (51.7%). Lead isotopes are the end-products of each of the three series of naturally occurring radioactive elements: Pb-206 for the uranium series, Pb-207 for the actinium series and Pb-208 for the thorium series. Forty-three other isotopes of lead, all of which are radioactive, are recognized.Divalent lead has a strong affinity for inorganic ions containing oxygen (eg, carbonate) or sulfur (sulfide). Lead can also complex with electron rich ligands in many organic cmpd such as amino acids, proteins, and humic acid.

Preventive MeasuresSRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.SRP: Contaminated protective clothing should be segregated in a manner so that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.The worker should wash daily at the end of each work shift, and prior to eating, drinking, smoking, etc. /Lead/For more Preventive Measures (Complete) data for LEAD FLUORIDE (6 total), please visit the HSDB record page.

TreatmentLead poisoning is usually treated with chelation therapy using DMSA, EDTA, or dimercaprol. (L21)
Gesundheitliche AuswirkungenLead is a neurotoxin and has been known to cause brain damage and reduced cognitive capacity, especially in children. Lead exposure can result in nephropathy, as well as blood disorders such as high blood pressure and anemia. Lead also exhibits reproductive toxicity and can results in miscarriages and reduced sperm production. (L21)
Unerwünschte WirkungenNeurotoxin - Predominantly motor
ExpositionspfadeOral (L136)inhalation (L136)dermal (L136)
ToxizitätsübersichtLead mimics other biologically important metals, such as zinc, calcium, and iron, competing as cofactors for many of their respective enzymatic reactions. For example, lead has been shown to competitively inhibit calcium's binding of calmodulin, interferring with neurotransmitter release. It exhibits similar competitive inhibition at the NMDA receptor and protein kinase C, which impairs brain microvascular formation and function, as well as alters the blood-brain barrier. Lead also affects the nervous system by impairing regulation of dopamine synthesis and blocking evoked release of acetylcholine. However, it's main mechanism of action occurs by inhibiting delta-aminolevulinic acid dehydratase, an enzyme vital in the biosynthesis of heme, which is a necesssary cofactor of hemoglobin. (T4, A20, A22, L136)
Signs and SymptomsSymptions of chronic lead poisoning include reduced cognitive abilities, nausea, abdominal pain, irritability, insomnia, metal taste in the mouth, excess lethargy or hyperactivity, chest pain, headache and, in extreme cases, seizures, comas, and death. There are also associated gastrointestinal problems, such as constipation, diarrhea, vomiting, poor appetite, weight loss, which are common in acute poisoning. (A2, L21)
Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ Contact can cause skin and eye irritation and burns. Inhalation can irritate the nose and throat. Lead fluoride can cause headache, irritability, mood changes, reduced memory, and disturbed sleep. The fluoride ion can cause protoplasmic poisoning at higher concn .../SIGNS AND SYMPTOMS/ While lead fluoride has not been identified as a teratogen or a reproductive hazard, lead and certain lead compounds have been determined to be teratogens and may also cause reproductive damage such as reduced fertility and interfere with menstrual cycles. Handle with extreme caution. Lead can accumulate in the body over a period of time. Therefore, long term exposures to lower levels can result in a build-up of lead in the body and more severe symptoms. These may include anemia, pale skin, a blue line at the gum margin, decreased handgrip strength, abdominal pain, severe constipation, nausea, vomiting, and paralysis of the wrist joint. Prolonged exposure may also result in kidney and brain damage. If the nervous system is affected, usually due to very high exposures, the resulting effects include severe headache, convulsions, coma, delirium, and death. In non-fatal cases, recovery is slow and not always complete. Alcohol ingestion and physical exertion may bring on symptoms. Lead exposure increases the risk of high blood pressure./SIGNS AND SYMPTOMS/ Not irritating to skin and mucous membrane. Solid irritating to skin and eyes./SIGNS AND SYMPTOMS/ If inhaled /dust/ will cause dizziness or loss of consciousness. If swallowed /solid/ will cause nausea, vomiting or loss of consciousness.

Antidote and Emergency TreatmentImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Lead and related compounds/Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Administer activated charcoal ... . /Lead and related compounds/Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or is in severe respiratory distress. Moderate hyperventilation (20 respiration per minute) may be beneficial for increased intracranial pressure. Start IV administration of 0.9% saline (NS) or lactated Ringer's (LR) /SRP: "To keep open", minimal flow rate/. For hypotension ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Lead and related compounds/Treatment. Emergency and supportive measures. Treat seizures and coma if they occur. Provide adequate fluids to maintain urine flow but avoid overhydration, which may aggravate cerebral edema. Avoid phenothiazines for delirium, as they may lower the seizure threshold. Patients with increased intracranial pressure may benefit from corticosteroids and mannitol. /Lead/For more Antidote and Emergency Treatment (Complete) data for LEAD FLUORIDE (6 total), please visit the HSDB record page.
